TLS4120D0EP V50

The TLS4120D0EPV V50 provides a 2A current capability, fixed 5V output voltage, and +/- 1.5% feedback voltage accuracy in PWM mode. Integrated features reduce external components, system costs, and board space. With a wide input voltage range (3.7V – 35V) and 100% duty-cycle operation, it suits automotive scenarios, offering low-current consumption in PFM mode and comprehensive protections.
